Step-Sibling Rivalry (Finn Wolfhard x Reader)

𝙳𝚊𝚝𝚎 ( 𝐈𝐈 )

Y/n's POV:

~ Saturday ~

" Okay see you later! "
Brand waved as he ran out of the school.

School on a Saturday? We had this stupid group project we had to finish before Monday,
which we thankfully finished.
Anywho...

I waved back and headed to the back door
since it was closer
to where my house was.
Oh, did I mention? During History, Jacob,
one of the popular high school jocks asked me out!
That's why I'm seeing Brand later since he's going to be the one to pick me up
and drop me off for my date.
Can't wait!
Yes, we were done with our project,
though I still have one main problem...
It's still fucking RAININGGG!
See I asked Brand of course if he could bring me home
but he had some errands to do with mom or something so I couldn't go...
"Son of a bitch."
I slumped on a locker when I suddenly heard some people laughing and
coming out of a classroom.
It was Finn and that bitch Sydney, laughing while they made out.
God, I just wanna fucking punch her in the fucking face!
Giving them a death glare Finn's smile disappeared
and he spoke to her and she kissed him goodbye,
but that's when he started walking towards me.
" Shit. "
I mumbled scurrying to stand up before he got me.
I made my way to hide in a classroom or something,
at least make him lose sight of me.
" Y/n! "
I heard Finn shout from behind.
Fucking hide somewhere Y/n!!!
I turned to a hall and opened the janitor's room since it was closest to me.
I hurried in and locked the door, and switched the lights off.
I took my phone out to use the flashlight, waiting to see if Finn-

Suddenly I heard the doorknob rattle,
" Go away, Finn! "
I shouted putting my phone away.
Now I wasn't sure how long I was going to stay in this closet for...
That's when the door opened, I couldn't see
who it was since the lights were off.
" Finn, leave me the fuck alone. "
I stood up, trying to find the light.
" Finn? "
I heard a male voice talk as the door shut.
" Y/n? It's Jacob. Are you okay? "
OH SHIT
He laughed as he switched the lights on, closing the door.
"Oh hi. I'm sorry I thought you were my step-brother. "
I pinched the bridge of my nose, awkwardly laughing.|
" Oh um.. "
Silence filled the air for a solid 10 seconds until he...
" Anyways, why are you here? I mean not that I don't want
you here but- I- I just wanted to make sure
our date was still on tonight. "
He smirked, stepping closer.
"Oh yeah, no, no it is."
I took a step back.
" Okay, sounds great. "
He looked down at me since he was a pretty tall dude.
I looked up and he started leaning in.

Oh shit, this is happening! Okay okay...

" Y/n! What the fuck!?
" We heard a muffled shout from someone outside.
"Who is that?"
Jacob turned around.
On the other hand, I already knew who it was.
" It's my fucking brother.
He's an asshole, I'm telling you. "
I sighed waiting for an answer as we stepped away from each other.
"Should I?"
He gestured to open the door.
" We don't have a choice. "
I shrugged my shoulders. Jacob opened the door, only for us to see
a pissed Finn standing by the door.
"What are you guys doing in here?"
He breathed heavily.
" I was just- "
" Never mind I don't wanna know. C'mon Y/n.
We're leaving. "
He interrupted Jacob, walking passed him, and dragged me out of the room
making a book fall out of my backpack
but luckily, I caught it.
" Finn. Can you ever learn to control
your fucking temper?
How did you even know we were fucking in there?!? "
I whisper-shouted while we turned to a different hall
but suddenly stopped.
" You guys were fucking in there!?!?! "
" No you asshole! That was an expression, dumbass! "
I hit his head with the book I had in my hand.
" There's a fucking window, Y/n! "
He made his point and maybe for once in his life,
he wasn't wrong.
There was indeed a small window that could peep into the janitor's room.
" Fuck. "
I sighed looking down.
" Now that you're in a place where I can
fucking communicate with you, why were you and that jerk Jacob
chatting in the Janitors closet? "
He asked in a serious tone, a look of disappointment on his face.

Why???

" Why the fuck would you wanna know, Finn?
You know I'm not actually,
your damn sister. "
I pried my arm away from him but he didn't say anything.
" Finn! "
I sang his name but he kept focus somewhere else,
he was looking at some classroom?
Probably something about that slut, Sydney.
"Finn!"
I slightly nudged him and looked at me.
" Stay here. I- I have to do something. "
He left me and headed to the same hallway we went out of.
"Yeah, go fuck your girlfriend some more!"
I yelled, my voice echoing through the halls.
I waited for about 5 minutes now- Wait.

Why am I waiting?

I sling my bag over my other shoulder and head out of the school.
It was still raining but I didn't fucking care anymore.
I dropped my bag to put my hoodie back on,
picked it back up, and walked home.
" You have got to be shitting me! "
I shouted as the rain just got heavier.
" Son of a bitch. "
I checked what time it was on my watch it was 1:12
in the afternoon already...
" Shit, mom's gonna kill me. "
I walked faster holding that would help.

~ 15 Minutes After Walking ~

I FINALLY made it back home!
I headed inside, took my shoes off, and ran upstairs to my bedroom.
Immediately I took a shower and changed into some warm clothes.
I heard a car pull up outside and it was Finn's car.
Isn't that just great...





AT:

Yes, Finn is an asshole...
